目的:探讨肝镰状韧带旁假性病灶的MSCT表现特征及鉴别诊断,提高该病变的诊断率。方法:回顾性分析2015年11月至2016年12月潮州市潮安区人民医院收治的35例已检出肝镰状韧带旁假性病灶,观察病灶边缘、形态及增强各期表现。结果:在检出的35个病例中,有3例病灶位于肝左外叶,其余32例位于肝左内叶,其中1例有二个病灶,其余均为单发病灶。病灶多呈小条片状,为22例,小类圆形6例,不规则形7例。最大病灶约12 mm×11 mm,最小病灶4 mm×3 mm。病灶密度均匀,无明显占位效应。其中33例在平扫时呈低密度度,计算机断层扫描(CT)值25~38 Hu,2例平扫呈等密度未见显示,为腹部常规增强扫描时检出。结论:肝镰状韧带旁假性病灶发生部位特殊,增强扫描门脉期几乎均呈低密度,界限清,在平扫及动脉期、延时期呈等或稍低密度,根据前述表现,通常可以做出诊断。
Objective: To investigate the features and differential diagnosis of MSCT in the lesions of the falx ligament of the liver and to improve the diagnostic rate of the lesions. Methods: From November 2015 to December 2016, 35 cases of pseudarthrosis of the liver sickle ligament were detected in Chaoan District People’s Hospital of Chaozhou City from November 2015 to December 2016. The margins, morphological changes and enhancement of the lesions were observed. Results: Of the 35 cases detected, 3 lesions were located in the left lateral lobe of liver and the remaining 32 were located in the left hepatic lobe, 1 of which had two lesions and the rest were single lesions. Lesions mostly strip strip, 22 cases, 6 cases of small round, irregular shape in 7 cases. The largest lesions of about 12 mm × 11 mm, the smallest lesions of 4 mm × 3 mm. Uniform density of lesions, no significant mass effect. Among them, 33 cases showed low density in plain scan, computed tomography (CT) value of 25 ~ 38 Hu, two cases of equal density showed no signs of plain scan, detected for conventional abdominal enhanced scan. Conclusions: The lesions of pseudarthrosis of the hepatic falx ligament have a special site. The enhanced portal venous phase showed almost the lowest density and the clear boundary. In the plain and arterial phase, the lag phase showed equal or slightly lower densities. According to the above findings, Can make a diagnosis.
